Description
The LMV321 (single), LMV358 (dual), and LMV324 (quad) are a low cost, voltage feedback amplifiers that consume only 80 μA of supply current per amplifier. The LMV3XX family is designed to operate from 2.7 V (±1.35 V) to 5.5 V (±2.75 V) supplies. The common mode voltage range extends below the negative rail and the output provides rail-to-rail performance.
The LMV3XX family is designed on a CMOS process and provides 1.2 MHz of bandwidth and 1.5 V/μs of slew rate at a low supply voltage of 2.7 V. The combination of low power, rail-to-rail performance, low voltage operation, and tiny pack-age options make the LMV3XX family well suited for use in personal electronics equipment such as cellular handsets, pagers, PDAs, and other battery powered applications.

FAQ
What is difference between voltage and current feedback?
Voltage feedback decreases the effect of load impedance on output voltage, and current feedback decreases the effect of load impedance on load current.
What is the use of voltage series feedback amplifier?
In Voltage-Series feedback, the input impedance of the amplifier is increased and the output impedance is decreased. Noise and distortions are reduced considerably.
What are the advantages of feedback amplifier?
Its advantages are:
It improves the stability of gain.
It increases the input impedance and reduces the output impedance.
It increases the bandwidth of the amplifier.
It reduces distortion and noise.
